Tell her you've had sex
Now, don't just walk up to her and say "I have had sex," but you do need to make it clear that you have banged a girl before (even if you actually haven't). You can mention it pretty bluntly, like "yeah so I was banging this chick once and..." but she will probably be disgusted and call you a pig. That's ok. Sooner or later, she will start thinking about what you said and realize that you're not a virgin and thus know how to please a woman or at least know where her vagina is. Girls need this reassurance so they know you won't cry after the first time you have sex together. A little while after you make it known that you've had sex, she'll text you with something asinine like "so... wut r u doin 2nite lol." Score.
